I am planning on turning my 110 Gallon into a Trigger only FOWLR. I currently have a very non aggressive O. Niger (towards anything he doesn't think he can eat in a few bites that is) . He is about 5-6 inches in length and non aggressive to just about every species he has encountered. (Tangs, Groupers, Rabbitfish, Eels, Lions). My question is what other types of triggers would you house in such an environment. I realize that in about 4-5 years I will need to upgrade to a 200-300 to house these giants. I have been looking at Blue Throats (male) and Pink Tails (maybe one of each). From what I have read those are non aggressive (normally) towards other triggers. Thinking 3-4 fish total, size ranging from 4-6 inches nothing bigger than my current fish. Thoughts?
